Relief Modular Valves MBP-01 MBA-01 MBB-01 01 Series Modular Valves
Features
The modular valves are functional elements with which a hydraulic system can be composed and built easily by stacking them with the mounting bolts. Therefore, no piping is required for the manufacture of the hydraulic systems.
Seric's 01 Series Modular Valves are widely used to compose the hydraulic systems for the various industrial equipment including machine tools, special purpose machines and injection moulding machines.
The valves have standardized mounting surface conforming to ISO 4401-AB-03-4-A and optimum thickness for the stacking.

★See the "Minimum Adjustment Pressure" of the next page for the item marked ∗.
Instructions
The minimum adjustment pressure equals the value obtained from the minimum adjustment pressure characteristics plus the tank line back pressure of the next page. This back pressure should include the value of the T-line pressure drop characteristics of the valves stacked to the base plate side of the modular valves.
To make pressure adjustment, loosen the lock nut and turn the pressure adjustment screw clockwise or anticlockwise. For an increase of pressure, turn the screw clockwise. Be sure to re-tighten the lock nut firmly after making adjustment to the pressure.
In case of a small flow, the setting pressure may become unstable. To avoid this, refer to the minimum flow characteristic curve of the next page and use the valve within a range as shown with.
